Abstract

The embodiment of the invention provides an untrusted bidirectional relay multi-antenna cooperative communication method and device, and the method comprises the steps: obtaining a received signal which is a signal received by a cooperative relay when a first node sends first information to the cooperative relay and a second node sends second information to the cooperative relay; calculating an optimal solution of an optimization problem model constructed according to the received signal so as to obtain an optimal solution of the relay parameter; and obtaining a sending signal according to theoptimal solution of the relay parameter, and sending the sending signal to the first node and the second node respectively. The embodiment of the invention provides an untrusted bidirectional relay multi-antenna cooperative communication method and device. By constructing the optimization problem model and obtaining the optimal solution of the relay parameters, the untrusted bidirectional relay multi-antenna cooperative communication is realized, the communication performance of the untrusted relay cooperation is improved in a multi-antenna scene, the information is protected from being leaked, and the simultaneous transmission of the wireless information and the energy is supported.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to an untrusted two-way relay multi-antenna cooperative communication method, device and storage medium. Background technique [0002] Cooperative relay communication is a kind of multi-user communication environment in which neighboring users can share each other’s antennas in a certain way to achieve cooperative relay transmission, so as to obtain spatial diversity gain, thereby reducing the system’s bit error rate and improving Communication method of transmission reliability. [0003] In the prior art, the relay cooperation system can be divided into one-way relay and two-way relay. In the half-duplex mode, the unidirectional relay cannot transmit and receive information at the same time, and the destination node needs two time slots to receive the information, resulting in a waste of half of the time slot resources. The two-way relay supports a g...
